Quote:Quote:What is bad about this thread still going? The logic kinda goes like this...On just about any other "Please help me with my mount" thread... where a mount owner states the they a frustrated that their mount is doing X when they think is should be doing Y... Within 5 or 6 responses, the original problem is identified and at least one or two common solutions are proposed and everyone goes on to the next thing.But with this mount (and this thread), and not to diminish the significant headway that has been made in any way, here we are 65 pages in and we are STILL struggling with a dual mode, PEC, 40# rated, mount that seems to have serious issues holding up a 25# OTA, even more serious issues tracking anything in polar mode for more than a few seconds, and now we are seeing PE graphs that look like a New Zealand seismograph.If after 65 pages and almost 1300 posts everyone is still debugging a mount, even if people continue to have "ah-ha" moments... Something is a little amiss.

I lost count of my scopes. Now I just want mobility. I came, I saw, I bought some interesting accessories, and put names to faces: NEAF 2012, ASAE 2012, SWAP 2013, ASAE 2013.
Quote: after reading for hours i still cant figure out what i am doing wrong. as i see others here using PHD and pempro with there lx80 mounts via ascom drivers and 505 cable. my set up is lx80 mount in eq audiostar with a3s4orion ssag with 50mm f3.4ascom platform 6 with meade lx200 clasic driver with PHD i get the same problem i see here without guiding the star will stay close to center for hours. but when i hit calabrate it starts moving up the screen and wont stop till i make it. with pempro after hitting the connect for mount and cam dosent matter witch way i tell the mount to slew using the arrow keys on scree it moves east then back for all for directions moves east only. hopefully i can get something worked out here. and also after upgrading to A3S4 there is a new setting under telescope ( german mount traning ) but i cant find any info anywhere on ho to do it. called meade and all i get is we will email you something but after 3 calls still no email. on a side note scope works great with starry nights and the sky. goto's work great thanks robert
Quote:I read the APM#909 is for the LX90. For the LX80, it's the APM#07509 - attached.
Quote:I'm guessing there aren't $5 worth of parts in it
Quote: I've got a 497EP with A3S4, in Polar mode, with PEC off.
Quote: Meade support told me the problem could be due to backlash and to train the drive.
Quote: I assume the procedure gives some kind of feedback, i.e. numbers?
Quote:I thought train drive was for backlash and smartdrive is for pec.
Quote:Gday Mark ( gotta stop calling you stew, sorry )As you note, to replace the worm with a lower pressure angle unit would require a new worm and wormwheel. Not sure it would cost more than the current design, as its probably just cut by a cnc machine, but its not what they have designed for.As to the geartrain, i really cant understand why Meade didnt use say the motor/Gbx from the LS units here and a belt drive.This would have given a very robust motor/gbx/encoder setup that could be easily set up and adjusted, compared to the cheap unadjustable plastic stuff in the LX80s now.Andrew

Quote:Gday Ed Quote:I'm fairly sure that I could have new high precision gears made for this mount But you still have the problem of the plastic gearbox housing and motor.Based on David Ds original photos of his failed DEC drive, the means to adjust the motor is 2 screws in a plastic housing hidden behind the encoder disk so you cant get at them.I still reckon a simple gearhead motor like in the LX200s/LSs and a belt drive would be a better fit in this case.That said, the LX80 gears look like they come from the LX90, so why are the LX80 ones showing such apparent variability in quality?? ( or are the later ones now better??? ) Quote:but I think that putting in better gears would only accentuate the other problems Nah, they are already accentuated. A good motor gearbox in the unit would at least make it more suitable for polar AP, but you would still be limited to light loads.Fixing the worm etc to increase the load capacity would still be negated ( in polar ) by the fact that the whole support of the RA axle is still a big cantilevered spring. The closer to the equator the user is, the worse it would get.Andrew Johansen Melbourne Australia
Quote:I'm guessing they weren't going to hit their price point with that design.
Quote: a good time for Meade to reexamine the LS mounts
Quote: If you do a drive train, in normal means you cannot see the results. If you load our patches, that allows inspection of a lot of data and hence you can dynamically read the data. Unpatched, you can still use my PEC editor to read the data, but it requires going into download mode to do it.
Quote:I'm unclear what you mean by 'numbers'. I don't see where the mount itself gives a status report, so I assume it has something to do with your patch &/or PEC editor.
Quote: There are ten choices ranging +0, +1, ..., +9. Do you know what these mean? % increase or other.
Quote: There are no negative numbers offered.

Quote:Nope; just inspires Andrew
Quote:Andrew, why, recognizing the limits of the mount, it would not be good enough for your purpose, grabngo dual solar ?
